SPACE-SAVING VIBRATION DAMPER INSTALLED INSIDE BEAM AND FRAME HAVING THE VIBRATION DAMPER

PROBLEM TO BE SOLVED: To provide a vibration control structure which is capable of freely providing an opening so as not to interfere with a wall surface configured by columns and beams, is easily manufactured at a low cost, and does not support a long-term load in the state where a member for supporting the long-term load is left plastically deformed in an earthquake.SOLUTION: The vibration control structure is provided in a junction of a column bracket and a beam member, and includes: a connection member whose one end is pinned to either one of the column bracket and the web upper end part of the beam member and whose other end is rigidly joined to the other one of the column bracket and the web upper end part of the beam member; and an energy absorption member whose one end is pinned or rigidly joined to either one of the column bracket and the web lower end part of the beam member and whose other end is joined to the other one of the column bracket and the web lower end part of the beam member through an energy absorption mechanism.
